  # Ideas ...

  #it 'should be able to search! (with pagination)'
  #it 'should default to getting additional pages when doing a search!'
  #it 'default rpp should be 100 (the max)'
  #it 'should have a nice method to call that will make a new watcher and start watching'
  #it 'should be able to watch! with pagination (will search! while there is a :next_page to request)'
